Pipe Detection Instrument

Chapter 1: Introduction

1. Significance of R&D

The research and production of underground pipeline detection equipment has a history of over thirty years in our country. While developing and manufacturing underground pipeline detection equipment, our company has been committed to the service and research of metal pipeline routing and fault testing technology for many years, solving many difficult problems for our clients and earning their trust and support. We have brought back field issues for targeted research, ultimately leading to the birth of the much-anticipated, domestically unique "Metal Pipeline Comprehensive Detection Instrument." The successful development of this product has resolved the long-standing issue of power supply departments searching for paths while carrying live electricity; it has also addressed the difficulty in accurately tracing the path of faulty pipelines; it has opened up a new field for metal pipeline routing, and broken the monopoly of foreign products in China.

Scope of Application 2

Since its launch, the product has been widely adopted in urban power supply bureaus, county power companies, railway power supply sections, large and medium-sized enterprises (including oil, chemical, coal, power plants, steel mills), educational institutions, property communities, city street lighting, highways, and communication maintenance departments. With our robust technical support, it plays a crucial role in rapid repair and quick location of underground pipelines for power supply and consumption departments.

3. Reminder

 Although the instrument is powerful in function and superior in performance, it remains a tool, an auxiliary tool for solving problems by humans. It cannot directly tell people the specific location of the circuit, but the operator can easily judge and draw conclusions based on the various information reflected by the instrument.

The company is committed to relentless efforts in product improvement and enhancement, continuously introducing new products with more advanced technology, superior performance, and comprehensive features. We will provide you with a solid material foundation and robust technical support in the fields of metal pipeline supervision and testing. Meanwhile, we hope to receive valuable feedback from our users.

To ensure safe and effective operation of this instrument, and to fully utilize its functions, please carefully read the user manual before using the equipment.

Chapter 2: Instrument Introduction

1 Working Principle

This instrument is a high-tech product designed based on the reflection principle of electromagnetic waves during transmission and the principle of electromagnetic induction, incorporating digital filtering, wireless reception, and software control.

Electromagnetic Induction: Its basic working principle is as follows: an transmitter generates electrical and magnetic waves, which are then transmitted to underground metallic pipelines through various transmission connections. Upon感应 to the electromagnetic waves, the pipelines produce induced currents on their surfaces. These induced currents propagate along the metallic pipelines towards a distance. During this propagation, the currents radiate electromagnetic waves back towards the ground. As a result, when an underground pipeline detector's receiver is used to detect underground pipelines, it receives electromagnetic wave signals directly above the pipelines on the ground. By analyzing the intensity variations of the received signals, the location and direction of the underground pipelines can be determined.

The conditions for this principle to be realized are: first, there must be a signal source capable of emitting sufficient electrical energy, which generates a current in the transmission line designed for electrical power. As the current flows, it also produces a magnetic field around the line; second, there must be a circuit capable of receiving this specific magnetic field, displaying the changes in the magnetic field as electrical signals.
